README

A MailChimp API wrapper using Guzzle v6 which implements a simple list subscription interface using the MailChimp v3 API.

By Simon Hampel.

Installation

The recommended way of installing MailChimp Subscribe is through Composer:

:::json
{
    "require": {
        "hampel/mailchimp-subscribe": "~1.0"
    }
}

Configuration

To use the MailChimp subscriber, you'll need to generate an API key using the MailChimp admin interface.

Log in to MailChimp and then go to Account by clicking on your username/avatar at the top and selecting Account from the menu.

Next, go to the Extras area and click on API Keys.

Click on the Create a Key button and give your new key a meaningful label so you know which one it is.

You'll also need to find the list ID of the mailing list you want to subscribe people to.

Click on Lists at the top and then click on your list name.

Click on the Settings submenu and select the List name and campaign defaults option.

Over on the right will be your List ID - make a note of this.

Usage

Initialisation

To start with, you'll need to create a MailChimp object which does the actual communication.

The quick way is to use the factory:

:::php
<?php
    use MailChimp\MailChimp;
    
    $apikey = 'YOUR API KEY HERE';
    
    $mc = MailChimp::make($apikey);

Alternatively, if you need more control, you can use the long-hand method:

:::php
<?php
    use GuzzleHttp\Client;
    use MailChimp\MailChimp;
    
    $apikey = 'YOU API KEY HERE';
    
    $config = MailChimp::getConfig($apikey);
    $guzzle = new Client($config);
    $mc = new MailChimp($guzzle, $apikey);

You'll also want to create a mailing list object to then work with the list:

:::php
<?php
    use MailChimp\MailingList;
    
    $listid = 'YOU LIST ID HERE';
    
    $list = new MailingList($mc, $listid);

We're now ready to work with our list.

Get Member

You can retrieve the details of a member by calling the getMember method of the MailingList class:

:::php
<?php
    var_dump($list->getMember('user@example.com'));

The getMember function returns false if the email address was not found in the list.

Get Member Status

Retrieve the current status of a list member by calling the getMemberStatus method:

:::php
<?php
    var_dump($list->getMemberStatus('user@example.com'));

Possible return values are: subscribed, unsubscribed, cleaned, pending - or false if the member was not found.

Check if Member Exists

You can check if a user is a member of a list with the isMember method, which returns a boolean result:

:::php
<?php
    if ($list->isMember('user@example.com'))
    {
    	echo "user is a member of our list";
    }
    else
    {
    	echo "user is not yet a member of our list";
    }

Subscribe a Member

Subscribe a new email address to your list using the subscribe method:

:::php
<?php
    var_dump($list->subscribe('user@example.com'));

To have MailChimp send a confirmation to the user before adding them to your list (double opt-in), set the second parameter to true: $list->subscribe('user@example.com', true)

You may also send an associative array of merge fields (name-value pairs) as a third parameter:

:::php
<?php
    var_dump($list->subscribe('user@example.com', false, ['FNAME' => 'Joe', 'LNAME' => 'Bloggs']));

Details about the subscribed user will be returned.

Unsubscribe a Member

To remove a user from the mailing list, use the unsubscribe method:

:::php
<?php
    var_dump($list->unsubscribe('user@example.com'));

Clean a Member

To clean an address from the mailing list, use the clean method:

:::php
<?php
    var_dump($list->clean('user@example.com'));

Cleaned addresses are addresses that have bounced too many times or are now considered invalid.
